HOSE-COUPLING.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed February 4, 1909. Serial No. 475,960.

To all whom 'tt may concern:

n .Be it known that I, VAJgNoEN P. citizen of the United States of America and resident of Mobile,in the county of Mobile b and State of Alabama, have invented certain new and useful Improvements in Hose- Couplings, of which the following is a specification.

This invention relates to certain new and useful improvements in hose couplings, and it has for its objects among others to provide an improved efficient hose coupling composed of few parts, in which thel employment of screw-threaded parts is practically dispensed with, there being but one member having threaded engagement with another.

A further object is to provide a coupling in which the parts are capable of manufacture at small cost and without complicated machinery, all of the parts being capable of being turned on an ordinary lathe, these parts readily assembled or disassembled when purposes and, when assembled and the parts coupled, endwise disengagement is prevented, yet a partial turn of the intermediate member couples or uncouples the parts. A tightening sleeve is provided for tightening the parts after they are coupled and also for locking them against accidental uncoupling. The parts are assembled by a longitudinal sliding movement one within the other and the members themselves arev of novel construction and adapted for coperation for the accomplishment of the desired end.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be pointed out in the appended claims.

The invention, in its preferred form, is clearly illustrated in the accompanying drawings, which, with the erence marked thereon, form a partof this specification, and in which* Figure 1 is a side elevation of my proved coupling with the imparts applied to substantially central longitudinal section through the coupling with the parts in coupled position. Fig. 3 is an elevation of the parts constituting the coupling, said parts being shown detached but in their relative positions. Fig. 4 is a sectional detail on the line 4 4 of Fig. 3. Fig. 5 is an end view of the body portion ofthe coupling. Fig. 6 is an end view of the coperating particularly numerals of refthe reception of the half or section of the coupling. Fig. 7 is a side elevation of the two members shown in Figs. 5 and 6 juxtaposed, the exterior memers being omitted. Fig. 8 is a longitudinal section through Fig. 7 an enlarged scale.

Like numerals of parts inthe several views.

eferring to the drawings,u1 designates whatA I term the body portion or member of reference indicate like Figs. 5 to 8 are on the coupling. AIt is formed at one end with an internal annular flange 2, the outer face of which forms a seat for the gasket, as seen in Fig. 2. At this end, the body ortion or member l is formed with the iianges or projections 3 extending inthe direction of the length of the member and flush with the outer periphery thereof. These flanges extend each substantially a quarter of the circumference of the Fig. 5, leaving spaces 4 between the adjacent ends of each two flanges. These flanges serve to prevent turning of the members relatively to each other when coupled. Near the midheight of the member 1, the same is reduced in diameter, as at 5, forming an annular shoulder 6 and adjacent said shoulder upon the larger diameter of the member is an annular liange 7 which, however, is not continuous but is interrupted, as shown at 8, forming the shoulders or abutments 9 and 10 for a purpose soon to be described. To facilitate application or assemblage of the parts, the outer end of this reduced portion 5 may 11, although it isevident that this feature may notalways be present.

sometimes be rounded, as seen atr member, as seen best in ling. It is formed interiorly with an annular shoulder or flange 13; in the face of the reduced portion 14 forming such shoulder is formed an annular groove or socket 15 having undercut wall, as seen best in Fig. 8, for packing ring or gasket 16 which, as before stated, has a bearing against the adjacent shoulder or seat formed sections of hose and coupled. Fig.V 2^is a 1 bythe internal annular collar 2 of the member 1. This' gasket may be cemented or otherwise retained within its socket or I may rely solely upon friction for retaining the said gasket against displacement.

17 is an exterior flange on the member 12,

`the outer face of which is rounded, as seen clearly in the different views, so as to avoid sharp corners, which latter have been found objectionable 1n that they interfere with the drawing of the hose through doors and over obstructions. It will be observed, particularly upon reference to Fig. 1, that in my coupling I dispense with all projecting parts, such as lugs for the reception of a spanner or other purposes and that I also avoid square or sharp corners, thus greatly facilitating handling of the hose, permitting the same the same or substantially so, as seen in Fig. 2.

The member 12 is formed at its end adjacent the gasket-socket portion with the ribs 19, each of which extends substantially a quarter of the circumference, as seen best in Fig. 6, leaving the spaces 2O between adjacent ends of the ribs. The ribs 19 each have one end tapered, as seen at 21, to facilitate engagement of the parts.

22 is a coupling sleeve. It has a milled periphery, as seen at 23, for an obvious purpose, and is provided with a reduced portion 24 provided with external right handed threads 25 and beyond the threaded portion it is formed with a reduced annular untlireaded portion 26 forming a shoulder 27 X at its junction with the threaded portion, and extending in the direction of the length of the sleeve at the outer end of the portion 2G is a lug 27 which has a rounded end, as seen at 28, and a shoulder 29 at the rear', as seen best in Fig. 4. At the opposite end this sleeve member is formed with ribs 30 which are oppositely disposed, as seen in Fig. 2. These ribs extend each substantially a quarter of the circumference of the member 22, leaving spaces 31 therebetween corresponding to the lugs 19 on the member 12. The ribs 30 each have one end rounded, as shown at 32, in Fig. 4, for the purpose of facilitating interengagement of the parts.

33 is a tightening and locking ring. It is roughened or milled peripherally, as shown at 34, and interiorly is threaded, as shown at 35, to engage the threads 25 of the coupling sleeve 22. The threads of this tightening and locking ring do not extend for the entire depth of the ring, but. terminate at a distance from the outer end so as to leave the annular fiat unthreaded portion 3G, for a purpose which will hereinafter appear. The outer end of the ring is rounded, as shown at 37, and provided with an internal annular` shoulder 38, as seen clearly in Fig. 2.

The parts are assembled as follows. The body portion 1 is inserted within the sleeve 22, the member 27 of the sleeve engaged within the space 8 between the ends 9 and 10 of the interrupted Hange 7 of the member 1, the said flange then having a bearing against the adjacent end of the sleeve upon which it may rotate within limits prescribed by the ends of the liange. The tightening and locking ring 33 is then applied over the outer end of the body portion 1, its inwardly turned end engaging with its shoulder 28 against the shoulder G of the member 1, as will be understood clearly upon reference to Fig. 2, and serving to exclude dust, dirt and all extraneous matter. A screw or the like 39 is then engaged in a threaded opening in the annular portion of the tightening and locking ring, the inner end of said screw being received in the unthreaded annular space 26 and in the unthreaded space 3G of the ring. This, however, is but one form of stop and it is to be understood that any other form of inward projection may be provided in lieu of the screw threaded into the ring. The body portion 1 with the sleeve and ring thus assembled is attached to the end of one member of the hose and the member 12 is attached to the end of the other hose section.

To couple the hose, the member 12 is brought with its lugs opposite the spaces between the lugs of the member 1 and then by giving either member a partial revolution so that the lugs of the two members are inter-engaged or interlocked and then by tightening up the ring 33, the parts are securely tightened in such intcrloclted position. In screwing up the tightening and locking ring, the stop pin 39 by reason of the circumferential freedom of motion which it has along the unthreaded space 2G permits slight endwise movement of the sleeve 22 before the lugs 30 tightly bind against the lugs 19 so as to compress the gasket and form a perfectly water-tight joint before the inner end of the portion 2G of the sleeve 22 binds against the annular flange 7 of the member l, thus compensating for wear in the gasket so as to always insure that the joint shall be tight. The shoulder 6 and the iiange 7 serve to limit the movements of the ring 33 and the sleeve 22 toward each other beyond prescribed limits.

In actual use, the forward movement of the ring 33 is arrested by the growing tightening caused by the iuterengagement of the locking parts.

In disconnecting the coupling, the ring 33 is revolved toward the left. The first effect of such revolution is to gradually release the pressure upon the gasket by slackening up the longitudinal strain on the sleeve 22. rIhis rotation is arrested by the engagement of the stop-pin 39 against the lug` 27. Further rotation of the ring 33 is transmitted to the sleeve 22 by means of the pin and lug in such wise that the ribs 3 are disengaged from the ribs 19 without the necessity of any separate operation and the hose sections are allowed to fall freely apart.

Modification in detail, proportion of parts etc., may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.
